Pain 2 Months Post RNY

I am 2 months post RNY. I had a laparoscopic surgery with no complications and a typical recovery. Now at 2 months post I suddenly have pain again. 

If I sit the pain is a 3.  If I stand, cough, sneeze, bend, etc. the pain goes up to a 5. The pain is localized around the main incision site and radiates to my back. 

This started after a day of typical, non-strenuous activities. The pain has been here for nearly 2 days now.  I have been combing the net and can't find any post-op complication that seems to fit. 

Has anyone had anything like this?  Thanks.
